HTC has reportedly confirmed a pesky bug impacting the audio on video recordings captured with Verizon Wireless’ new HTC ThunderBolt smartphone. The bug, according to several ThunderBolt owners who have taken to forums to discuss the issue, causes the audio to be muffled on video files captured using the device’s camcorder function. The bug is intermittent, so only some video recordings are affected. According to enthusiast blog Android Central, HTC has acknowledged the issue and has stated that a fix is currently in the works. In the meantime, third-party video recorders are seemingly unaffected by the bug, so there are several alternatives that can be used until HTC releases its fix.
